BILL-BOOK AND RECORD BINDER.

Specification of Letters Patent.

Patented Jan. 31', 1911.

Application filed May 25, 1910. Serial No. 563,298.

To all whom it may concern:

Be it known that I, OTTO C. MAN'rnUrnL, a citizen of the United States,residing at Milwaukee, county of Milwaukee, and State of lVisconsin,have invented new and useful Improvements in Bill-Book and RecordBinders, of which the following is a specification.

My invention relates to improvements in a so called bill book and recordbinder, for which Letters Patent, No. 953046, was issued to me March 29,1910, and said improvements pertain more especially to the constructionof the parts referred to in said patent as binding needles by which aseries of perforations are first made through the sheets of blockedpaper preparatory to securing the same together with a binding cord, andby which device the cord is drawn through such perforations preparatoryto securing the paper thus blocked together. As heretofore constructedand shown in said patent, the binding needles are made solid and areadapted to puncture a hole through the paper without removing anyportion of the same, whereby it became diflicult to draw the bindingcord through such perforations. By my improvement, however, the needlesare each provided with a cylindrical cutting instrument, which isremovably attached thereto and is adapted to cut out and remove aportion of the paper as it is forced into the same, whereby a clean cutaperture is formed for the rece tion of the binding cord.

My invention is "urther explained by reference to the accompanyingdrawings, in which Figure 1 represents a perspective view of a series ofbinding needles supported from a block of paper as the same is heldpreparatory to being bound together. Fig. 2 is a perspective view insection of a block of paper showing the arrangement of the binding cordas it appears after being drawn into the perforations, preparatory tobinding such sheets of paper together. Fig. 3 is a side view of one ofthe needles provided with a cylindrical cutting instrument shown invertical section, and Fig. 4: is a longitudinal section of a modifiedform of needle provided with a central opening for the passage of wastepaper which is removed in forming the apertures.

Like parts are identified by the same reference numerals throughout theseveral views.

1 represents a block of sheets of paper secure together, preparatory toforming a series of perforations therein.

2 is a needle and 3 is a cylindrical cutting instrument, which isadapted to be removably connected wit-h the upper end of the needle asthe perforations are being formed through the blocks of paper. Thecutting instrument comprises a hollow cylindrical portion 4 and opposingcutting blades 5, 5, which terminate at their upper ends with sharppuncturing points 6, G.

8 is an aperture formed in the side of the cutting instrument throughwhich the small disks of paper escape from the instrument, as the sameis being forced through the block.

It will be understood that when the needles are used, as shown in Fig. 1for perforating the blocked sheets, they are each provided with acutting instrument 3, while being forced through the paper. \Vhen,however, they have penetrated the block of paper, as shown in Fig. 1,the cutting instrument 3 is removed from all of said needles as shown at10, 10, in said Fig. 1, whereby the binding cord 11 is readily insertedin the hook or angular recesses 12 of said needles, preparatory todrawing the cord 11 through the apertures 13 of the paper as shown inFig. 2. As heretofore constructed and shown in said patent, the needles2 are made pointed at their upper ends and were adapted to puncture thepaper without removing any portion of the same, and for this reason, itbecame di'flicult as stated, to draw the folded binding cord backthrough the perforations as the needles were withdrawn. B myimprovement, however, it will be unc erstood that the cutting blades 5,5, are adapted to sever the paper when the parts thus severed passbetween said cutting blades and out through the side aperture 8, wherebya smooth aperture is formed through the paper for the reception of thebinding cord.

The modified form shown in Fig. 4; comprises the cylindrical member 16,cutting blades 17, 17 and puncturing points 18, 18, and the sideaperture 8 is dispensed with, and the severed paper is free to pass upthrough the cylindrical opening 14: of the cutting instrument, and suchdevice is preferably provided with a handle 15 which for such purposeserves as a substitute for the needle by which the blades may bemanually per end of said needles 2 are provided upon two opposing sideswith flattened surfaces 22, which are turned at right angles to theshoulder of the cutting instrument as said instrument is being placedthereon. hen, however, said cutting instruments are in place, as shownin Fig. 3, they are turned a quarter of a turn on said needles, wherebythe inwardly projecting shoulder 20 is caused to engage in the opposingrecesses 21 of the needle and thus temporarily lock the cuttinginstrument thereto as the same is being inserted through the paper. Itwill of course be understood that preparatory to disengaging saidcutting instruments from the needles, they are turned a quarter of aturn in the opposite direction whereby the shoulder 20 is disengagedfrom said recess, when said instruments are readily withdrawn.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. In a device of the described class, the combination of a hollowcylinder, a pair of cutting blades formed integrally with said cylinderterminating at their ends with sharp penetrating points, and a needleprovided near one end with a cord receiving hook, said needle beingadapted to be used for forcing said cutting blades and cylinder througha block of paper, said hook being adapted, when said cylinder and bladesare removed, to engage a binding cord and draw the same into theperforations formed by such blades.

2. In a device of the described class, a series of needles, eachprovided at one end with a cord receiving recess, a cut-ting instrumentfor each of said needles comprising a cylindrical member adapted to bere inovably secured to each of said needles, and means for temporarilylocking said cutting instrument to said needle, said cutting instrumentbeing provided with a pair of cutting blades terminating at their endswith sharp puncturing points, all substantially as and for the purposespecified.

In testimony whereof I afiix my signature in the presence of twowitnesses.

OTTO C. MANTEUFEL.
